摘要： The present invention relates to an MCF with a structure for enabling an alignment work with higher accuracy. The MCF has a plurality of cores and a cladding. An outer peripheral shape of the cladding in a cross section of the MCF is comprised of a circumferential portion forming a circumference coincident with an outer periphery of the MCF, and a cut portion. The cut portion has a bottom portion and two contact portions provided on both sides of the bottom portion and projecting more than the bottom portion. When a side face of the MCF is viewed, the two contact portions have flattened faces and the flattened faces of the two contact portions extend along a longitudinal direction of the MCF with the bottom portion in between.

摘要： An embodiment relates to a method for manufacturing an optical module having an MCF and two connection components, and enables rotational alignment of the MCF to be implemented with high accuracy even in short-haul optical wiring. The MCF is arranged in a region between the two connection components while an end thereof projects from one connection component. As this arrangement state is maintained, array positions of cores in the projecting end are observed from a side face and the MCF is rotationally aligned by a rotation grasp jig grasping the projecting end to adjust the array positions of the cores, based on the observation result.

摘要： An embodiment of the invention enables each core in an end face to be readily identified by observation of either one end face, regardless of the presence or absence of a twist of a pertinent MCF and difference of ends. In a cross section of the MCF, a core group constellation has symmetry but each core in a core group is identifiable by breaking of all types of symmetry in a common cladding, defined by a combination of the core group constellation with the common cladding, or, by making the fiber ends distinguishable.

摘要： A multi-core optical fiber 1A in which a plurality of cores can easily be identified even in the case where they are symmetrically arranged in its section has seven cores 10 to 16, a visual recognition marker 20, and a shared cladding 30 enclosing the seven cores 10 to 16 and the visual recognition marker 20. The cores 10 to 16, the visual recognition marker 20, and the cladding 30 are respectively made of silica glass as their main element. The cores 10 to 16 and the visual recognition marker 20 extend along the fiber-axis direction. The respective refractive index of the cores 10 to 16 is higher than the refractive index of the cladding 30. The refractive index of the visual recognition marker 20 differs from that of the cladding 30. In the cross-section perpendicular to the fiber-axis, the cores 10 to 16 are arranged such that they have 6-fold rotational symmetry and line symmetry. The visual recognition marker 20 is arranged at a position which breaks such symmetry.
